Abstract

This paper deals with a discussion of the morphological correlation between the photospheric transversal magnetic field(PTMF) observed at Beijing Observatory and the penumbral filaments(PF) observed at Yunnan Observatory in eight areas of the largest active region AR5395 for the period of 9-15 March 1989. The morphological correlation is rouphly divided in three grades:"consistence", "approach"and "cross", "consistence" means that the difference of the azimuthal angles of PTMF and PF is smaller than 20°; "approach" means that the difference is in the range of 20°and 40°; "cross" means that the difference is more than 40°.
